Returns true if the key fires a keypress event in the current browser.
Accoridng to MSDN [1] IE only fires keypress events for the following keys:

Safari is similar to IE, but does not fire keypress for ESC.
Additionally, IE6 does not fire keydown or keypress events for letters when the control or alt keys are held down and the shift key is not. IE7 does fire keydown in these cases, though, but not keypress.
